Seems wise, the MDD and D series default can addresses are in the same range it seems. The MoTeC can address document says that the MDD address range can be changed by changing links on the pcb, but I don't know how that's done.
For the D153 you can turn off the default messaging or change the address to whatever you want. In Display Creator, go to the settings tab and under 'Hardware Configurations' select either 'Off' or 'User Assign"
